Heat maps/multiple values

Question

I'm trying to learn a bit about heat maps.  I was curious if multiple values could be shown.  Specifically, I have voter political parties (represented by blue and red dots).  Can I create a heat map that shows the density of their locations?  Thanks in advance.

AGOL = ArcGIS Online, API means application programming interface. You can see the list of available API's and SDK's (Software Development Kits) here: ArcGIS for Developers

An example of a heatmap using the JavaScript API can be found here:

Explore Heat Maps | ArcGIS API for JavaScript

A heat map is basically a type of visualization while dot density and hot spot analysis are real types of analysis. A very useful resource is the blog post by Lauren Rosenshein‌:

Kind regards, Xander

I was going to use the point density command.  Not sure what AGOL or API are.  What would you recommend?

Just to be sure, where and how are you going to create the heatmap? Using Esri Maps for Office (can't upload the heatmap to AGOL) or using an API (like js). In AGOL you have analysis options to create hotspots, but be aware that heatmap is a visualization type while hot spot is an analysis.
